LAnnPoint::SetBitmap

#include "ltwrappr.h"

virtual L_INT LAnnPoint::SetBitmap(pBitmap, uFlags=0)

virtual L_INT LAnnPoint::SetBitmap(pBitmap, uFlags=0)

LBitmapBase * pBitmap;

/* pointer to an LBitmapBase object */

pBITMAPHANDLE pBitmap;

/* pointer to the bitmap handle */

L_UINT uFlags;

/* flags that determine the object to process */

Sets the bitmap of the annotation object.

Parameter

Description

pBitmap

Pointer to the bitmap object referencing the bitmap object to assign to the specified object.

pBitmap

Pointer to the bitmap handle referencing the bitmap to assign to the specified object.

uFlags

Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values:

 

Value

Meaning

 

0

Process only the specified object.

 

ANNFLAG_SELECTED

ANNFLAG_NOINVALIDATE

[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.

Example

This is an example for both forms of LAnnPoint::SetBitmap(pBitmap, uFlags=0):

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName
L_INT LAnnPoint_SetBitmapExample(HWND hWnd)
{
   ANNPOINT annPoint = {50,50};
   ANNRECT  annRect =  {50,50,150,150};
   LSettings::UnlockSupport(L_SUPPORT_DOCUMENT, L_KEY_DOCUMENT);
   LAnnPoint *pMyAnnPoint = new(LAnnPoint);
   pMyAnnPoint->SetPoints(&annPoint);
   pMyAnnPoint->SetVisible(TRUE);
   //Change LAnnPoint bitmap
   LBitmapBase MyBitmapBasePrimary;
   MyBitmapBasePrimary.Load(MAKE_IMAGE_PATH(TEXT("image1.cmp")));
   pMyAnnPoint->SetBitmap (&MyBitmapBasePrimary,0);
   //Another way to change the bitmap
   pMyAnnPoint->SetBitmap(MyBitmapBasePrimary.GetHandle(),0);
   //Create container and insert annotation
   LAnnContainer m_AnnContainer; 
   m_AnnContainer.Create(hWnd, &annRect, TRUE);
   m_AnnContainer.Insert(*pMyAnnPoint);
   m_AnnContainer.SetUserMode(ANNUSER_RUN);
   return SUCCESS;
